IMPRVEMENT IN STEAM-nurses.

To all whom nit 'may concern.-

Be it known that I, FRANCIS BRAGKNEY, of the city'of Baltimore and State of Maryland, have invented certain Improvements in Apparatus for Radiatin g Heat, adapted to the heating of apartments and buildings, of which the following` is a specification 5' and I do hereby declare that the same is a full, clear, and

ence being had tothe accompanying drawing My invention relates to a steam or hot-water chamber for the purpose of radiating heat, adapted to be used, singly or in benches or gangs, as direct or indirect radiators, having,

ing-surface, two exterior and two interior surfaces upon the outside of the chamber, more are provided with tapering projections, those on one surface alternating in their positions with reference to those upon the opposite surface, so that the spaces between one series of these projections are opposed by the similar projections upon the opposite surface.- The object of these projections and -their alternate positions with reference to each other is to separate or reduce the volume of the current otl air in its passage through the spaces formed be heated.l In order to promote the thorough circulation of the steam 4around all portions of the interior surfaces of the chamber, and in some degree to oppose the ordinary velocity of its passage through an open duct, I place within the chamber certain diaphra gms, around which the steam must circulate in its course for securing the chambers together in such series, and for closing the openings in theend chambers of the benches or gangs with suitable bonnets or heads.

In the further description of my invention which follows, duereference must be had to Figure lis a part sectional and part nonsectional plan of two chambers tted together, and Fig. 2 is a side elevation of a chamber with one-half of the closing-bonnet removed.

Similar letters of reference indicate similar parts of the'invention in both figures.

Af is the chamber, of which A A' are the inbefore named. The tapering alternate projections are represented by a, and the opposing spaces by a. As shown in Fig. 2, the

spaces are narrower at the bottom than at the are the openings through which the steam or hot water is admitted withinV the chambers. The openings are covered by the bonnets C', having the projection d fitted within the recess d, wherein a suitable gasket is inserted. One side of the chamber has the recess df, to which the projection d of the adjacent chamber is fitted with a gasket. The openings O are within the solid center C, andin the center of each opening is th'e bolt e, extending through the entire series of chambers and connecting them together in benches or gangs. These chambers, singly or in vertical or horizontal gangs, may be used as directradiators when placed within the `rooms or apartments 'to be heated. When placed in cellars or elsewhere, and provided with external casings and pipes leading to other partsoi the buildphragms B situated so as directly to oppose and conduct the steam or water entering centrally at O to the ends of the receptacle, and having as the exterior surfaces thereof the sides 'A' and B', herein called external and internal, provided with the tapering alternating projections a, together with the solid center C" v perforated with the openings O,'the lowest point of which openings reach-cs to zr, the whole constructed, arranged, and to operate substantially in the manner set forth.
